successful one if previous BIOS flashing process fails. However, before doing this, one Crisis Disk should be
prepared in WinXP. Detailed steps are as the followings:
a. Prepare the Crisis Disk in WinXP.
b. Insert the Crisis Disk to a USB floppy drive which is attached to the failed machine.
c. While the system is turned off, press and hold Fn+ESC, then press Power Button. The system
should be powered on with Crisis Recovery process.
d. BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
e. If the flashing process is finished, a long beep should be heard.
f. Power down the system after you hear the long beep.
If the crisis recovery process is finished, the system should be powered on with the successful BIOS. RD/CSD
can then update the BIOS to a workable one by regular BIOS flashing process.
